JPH0920647A - Skin cleaning agent - Google Patents

Abstract

PURPOSE: To obtain a skin cleaning agent for face washing, massaging, etc., having excellent waste-removing effect and giving good feeling to the skin. CONSTITUTION: This cleaning agent contains 0.01-5wt.% of spherical resin powder (e.g. spherical polyethylene) and 0.01-5wt.% of fiber (e.g. nylon wool). The weight ratio of the fiber to the spherical resin powder is preferably 1:(25-2.5). Preferably, the diameter of the spherical resin powder is about 50-300μm and the length of the fiber is about 0.1-5mm. The agent is preferably further incorporated with a granular substance (e.g. fine crystalline cellulose). The agent is properly compounded with humectant, thickener, drug component, colorant, dispersing agent, perfumery, etc., in addition to the above components. The addition of the fiber causes the entanglement of the waste with the fiber to promote the separation of the waste from the skin and the fiber softens the feeling to the skin by preventing the direct contact of the scrubbing agent to the skin.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skin cleanser, and more particularly, it has excellent feeling of use and excellent cleaning effect or massage effect capable of effectively removing waste products generated on the skin surface. Regarding skin cleanser.

[0002]

2. Description of the Related Art As a skin cleansing agent used as a skin cleansing or massage cosmetic, there is a scrubbing agent. The skin cleanser containing this scrubbing agent is mainly intended to remove waste products generated on the skin surface. That is, when extra keratinocytes that should originally be exfoliated are generated as a waste product on the skin surface due to a failure of the skin's self-sustaining activity, such a waste product cannot be completely removed by a normal cleansing agent or the like. Therefore, by using a skin cleanser containing a scrubbing agent, when the scrubbing agent rolls on the skin surface, the waste material is lifted from the skin surface and separated to remove the waste material.

As a scrubbing agent to be added to such a skin cleansing agent, spherical resin powder such as spherical polyethylene or crushed polyethylene has been conventionally used.
A skin cleanser containing only a scrubbing agent,
There was a problem in the feeling of use, such as when the scrubbing agent directly contacted the skin and the stimulating sensation of the massage was too strong, or when the skin contact was very strong, the scrubbing agent had to be adjusted to the extent that it did not hurt and gommage. Further, although it is said that the effect of removing waste products is superior to that of a cleansing agent by blending a scrubbing agent, the present situation is that further improvement of the effect of removing waste products is desired.

[0004]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above circumstances, and in a skin cleansing agent containing a scrubbing agent, it has a more excellent effect of removing waste products, and a facial cleansing agent which is excellent in usability. The purpose is to provide a skin cleanser for massage and the like.

[0005]

Means for Solving the Problems As a result of intensive studies to solve the above-mentioned conventional problems, the present inventors have found that a skin cleansing agent containing a scrubbing agent further contains fibers. It was found that the above object can be achieved by the above, and the present invention has been completed based on this finding.

[0006] That is, according to the present invention, there is provided a skin cleansing agent characterized by containing a spherical resin powder and fibers.

The skin cleansing agent of the present invention will be described in detail below.

The spherical resin powder used in the present invention means that used as a scrubbing agent in a skin cleansing agent generally used as a facial cleanser or a cosmetic composition for massage. Specifically, spherical polyethylene, spherical polyester, spherical nylon and the like are used, and spherical polyethylene is particularly preferably used, but the present invention is not limited thereto. These spherical resin powders may be used alone or in combination of two or more.

The amount of the spherical resin powder compounded is preferably 0.01 to 5.0% by weight, more preferably 0.05 to 3.0% by weight, based on the total amount of the skin cleansing agent. If the blending amount of the spherical resin powder is less than 0.01% by weight, it is difficult to obtain a sufficient scrubbing effect, while the blending amount of the spherical resin powder is 5% by weight.
If it exceeds, the texture is inferior and the skin feels poor. Also, this spherical resin powder has a particle size of 50 to 300 μm.
Those having a diameter of about m are preferably used, and particularly, a particle diameter of 150 to 2
It is preferably about 50 μm.

The present invention is characterized in that fibers are further added to the scrubbing agent (spherical resin powder). The fiber used in the present invention is not particularly limited as long as it can be used in the field of cosmetics and the like, and for example, synthetic fiber-based fiber, natural fiber-based fiber or the like can be arbitrarily used. For synthetic fiber type,
Examples thereof include polyamide (nylon-based), polyacryl, polyester, polyvinyl alcohol, polyvinylidene chloride, polyvinyl chloride, polyethylene and the like. Examples of the natural fiber type include wool, silk, cotton, and hemp. Among these, nylon such as 0.5 denier nylon pseudo hair, 1.5 denier nylon pseudo hair, and 11 denier nylon pseudo hair are particularly preferably used.
The length of the fibers used is preferably about 0.1 to 5 mm, more preferably about 0.5 to 2.5 mm. These fibers may be used alone or in combination of two or more.

In the present invention, by blending this fiber, when the skin cleansing agent is applied to the skin and used, the fiber has a function of being entangled with waste products on the skin surface and separating from the skin. Then, the scrubbing agent rolls over the waste material thus separated from the skin, so that the stubborn waste material is raised from the skin and separated from the skin. That is, due to the synergistic effect of entanglement of fibers with waste and separation of waste by the scrubbing agent,
As compared with the case where only the conventional scrubbing agent is contained, a more excellent waste product removing effect can be obtained.

Further, when only the scrubbing agent is blended, the scrubbing agent hits the skin and hurts during use, and therefore, it was necessary to control the force during gommage. However, in the present invention, the fibers can prevent the scrubbing agent from directly contacting the skin, so that a mild feeling of use can be obtained.

The amount of this fiber blended is preferably 0.01 to 5.0% by weight, more preferably 0.3 to 2.0% by weight, based on the total amount of the skin cleansing agent. The amount of fiber is 0.01
If the amount is less than 5% by weight, the effect of the present invention cannot be sufficiently obtained. On the other hand, if the amount of the fibers added exceeds 5% by weight, the feeling of use is heavy and it is not preferable.

The compounding ratio (weight ratio) of the fibers to the spherical resin powder is as follows: fiber: spherical resin powder = 1: 25 to 1:
It is preferable to mix them in a ratio of 2.5, and more preferably 1: 7 to 1: 3.

In the present invention, in addition to the spherical resin powder and the fibers, it is preferable to further mix a granular substance. Examples of the granular substance include fine crystalline cellulose and the like. This fine crystalline cellulose, together with the above fibers, can more effectively perform the function of entwining skin waste products.

The base, properties, etc. of the skin cleansing agent containing the spherical resin powder and fibers as described above are not particularly limited, but a creamy one containing clay mineral is preferable.

Any clay mineral can be used as long as it is used in so-called clay-based cosmetics. Specific examples include talc, kaolin, mica, montmorillonite-based aluminum silicate, and the like. Among these, 1 type (s) or 2 or more types can be used. Since clay has a property of adsorbing fat, the use of clay base can adsorb excess sebum on the skin surface and unnecessary intercellular lipids.

In the skin cleansing agent of the present invention, a moisturizing agent generally used in cosmetics is used within a quantitative and qualitative range that does not impair the quality such as appearance stability and viscosity and does not impair the effects of the present invention. A viscous agent, a drug, a colorant, a dispersant, a perfume and the like can be added.

Examples of the moisturizing component include dynamite glycerin, 1,3-butylene glycol, dipropylene glycol, propylene glycol, glycerin, xylitol, sorbitol, maltitol, hyaluronic acid and the like.

As the thickener, laponite, kunipia,
In addition to montmorillonite clay minerals such as bee gum and benton, sodium alginate, hydroxyethyl cellulose, hydroxypropyl cellulose, polyvinyl alcohol, hydroxymethyl cellulose and the like can be mentioned.

The skin cleansing agent of the present invention as described above can be produced in the same manner as a skin cleansing agent containing a usual scrubbing agent.

As an example of the method of using the skin cleansing agent of the present invention, for example, after washing the face, take a small amount on the fingertips, spread it thinly on the entire face while drawing a circle so as to entangle with the waste, and leave it for 5 to 10 minutes. After drying, rinse the scrub with water or lukewarm water in a circle as if rolling it on your skin. In the present invention, since the fibers are mixed in addition to the spherical resin powder (scrub agent), the fibers can make the skin contact with the scrub agent mild and improve the feeling of use. In addition, the synergistic effect of the two effects of entangled skin waste with fibers and rolling the scrubbing agent onto the skin to peel off the entangled waste from the skin, results in more complete removal of the waste. It can be performed.
